Abstract
The invention discloses a pin roll mounting, retreating and locking device, which comprises a pull rod, one or more than one locking baffle plate and one or more than one lock plate, wherein, one end of the pull rod is connected with the pin roll; one or more than more pin locking baffle plate is fixed on the pull rod; and one or more than one lock plate makes the locking baffle plate and the position where the pin roll is positioned connected and fixed with each other. The pin roll mounting, retreating and locking device can realize the mounting, retreating and locking of the pin roll in the inside of a harsh environment, a narrow space or a complex structure at a long distance.
Description
Technical field
The present invention relates to heavy machinery and field of metallurgical machine, particularly a kind of bearing pin dress moves back and locking device.
Background technique
Need often lock in rugged environment, small space or labyrinth inside with unclamp be connected the width of cloth than the loose pin axle, particularly lock and unclamp wherein used when axle, usually operator must be in the tight or small space of abominable ring or offer the technology hand hole, with Work tool knock, lifting gear cooperates and realizes the dress axle or move back axle work.Its complicated operation and inconvenience are carried out.
Summary of the invention
The purpose of this invention is to provide and a kind ofly realize that at a distance the bearing pin in the above-mentioned environment being adorned the bearing pin dress that moves back and lock moves back and locking device.
The objective of the invention is to be achieved through the following technical solutions:
A kind of bearing pin dress moves back and locking device, and it comprises:
The pull bar that one end is connected with this bearing pin;
Be fixed on this pull bar one or more and lock baffle plate;
One or more interconnect this device that locks baffle plate and this bearing pin place and fixing jam plate.
Wherein, its pin plate is made up of interior pin plate and outer pin plate, and inside and outside pin plate is separately positioned on and locks the baffle plate both sides.
Wherein, it comprises that also one fastens the lock(ing) bolt that connects by exterior lock plate mutually with interior jam plate internal thread.
Wherein, this jam plate is fixed on this device by a synchronizing shaft and a baffle plate.
Wherein, be welded with the leader on the outer surface of this exterior lock plate.
Wherein, this pull bar is fixedlyed connected by screw thread with this bearing pin, and between also is provided with a nut.
Wherein, also be provided with the leader on this pull bar.
Wherein, the part between this pull bar upper pin and the locking baffle plate also is provided with an open baffle.
Positive progressive effect of the present invention is:
It can realize at a distance the bearing pin of rugged environment, small space or labyrinth inside being adorned moving back and locking.
Description of drawings
Fig. 1 moves back for bearing pin dress and the bearing pin of locking device locks structural representation under the state;
Fig. 2 move back for bearing pin dress and the bearing pin open state of locking device under structural representation;
Fig. 3 is the structural representation under the lock state of locking device;
Fig. 4 is the structural representation under the open state of locking device.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
Fig. 1 and Fig. 2 are that the bearing pin dress moves back and the locking of locking device and the structural representation under the open state.This device is made up of bearing pin 1, nut 2, pull bar 3 and locking device 4.Pull bar 3 heads have outside thread, and there is internal thread bearing pin 1 end, and nut 2 and bearing pin 1 are contained on the pull bar 3 by screw thread simultaneously, by the mutual extrusion of nut 2 with bearing pin 1, thereby guarantee that bearing pin 1 and being connected firmly of pull bar 3 are difficult for getting loose.Pull bar 3 is provided with open baffle 8, locks baffle plate 11 and handle 12, is to be welded to connect.Locking device 4 is provided with interior jam plate 9, exterior lock plate 10, handle 13, lock(ing) bolt 14 and synchronizing shaft and baffle plate 15 etc.Interior jam plate 9 and exterior lock plate 10 are installed on the device framework outer panel both sides at this bearing pin place by synchronizing shaft and two baffle plates 15, handle 13 is welded in surface outside the exterior lock plate 10, lock(ing) bolt 14 can pass exterior lock plate 10 and framework outer panel, tightens with the screw-internal thread fit of interior jam plate 9.
When needs are installed bearing pin, only need driving handle 12, make device slide onto Fig. 1 and lock state by Fig. 2 open state, shake handle 13 then, make locking device 4 go to the locking state of Fig. 3, at last lock(ing) bolt 14 is passed exterior lock plate 10 and framework outer panel and rather tightly on interior jam plate 9, get final product by the releasing orientation of Fig. 4.Bearing pin is just become by open state and locks and lock state like this, this state down in jam plate 9 and exterior lock plate 10 from the inside and outside baffle plate 11 that blocks on the pull bar, the axial freedom of bearing pin has been limited, can not skid off axis hole easily and causes the accident.
When needs are released bearing pin, only need unclamp lock(ing) bolt 14, shaking handle 13 makes locking device 4 be gone to the releasing orientation of Fig. 4 by the locking state of Fig. 3, spur handle 12 then, make device slide onto Fig. 2 open state by Fig. 1 state of locking, shake handle 13 at last again, make locking device 4 go to the locking state of Fig. 3, lock(ing) bolt 14 is passed exterior lock plate 10 and the framework outer panel rather tightly gets final product on interior jam plate 9 by the releasing orientation of Fig. 4.Though bearing pin has become open state like this, interior jam plate 9 and exterior lock plate 10 are from the inside and outside baffle plate 8 that blocks on the pull bar, and axial freedom is limited equally, can not cause the accident because slip comes off.
